The software has been working well for us. The combination of Ansys, the material data we have obtained and the ability to perform fatigue simulations has allowed us to design products that would not have been possible previously (without extensive physical testing)

The Northern City Line of the Great Northern Network Rail system in the United Kingdom started operation in 1904. Since 2015 the line has run a minimum of six trains per hour and extended operating hours until midnight.

英国大北方铁路网络北城线于1904年投入运营。自2015年起，该线路每小时至少运行六班列车，运营时间延长至午夜。

Noise complaints from residents near the Moorgate Branch rose to the attention of London’s Mayor and political pressures resulted in a budget being formed to deal with noise complaints — and Network Rail dedicating a team for a quick solution.

Moorgate支线附近居民的噪音投诉引起伦敦市长关注，政治压力促使预算拨款以应对噪音问题，Network Rail组建团队寻求快速解决方案。

Delkor Rail’s challenges included maximizing N&V reduction, maintaining TOR, using the existing hole centers, retaining BH rail and key protocols, and completing all work through EN13481 Cat C testing. All while assuring sufficient durability.

Delkor Rail面临的挑战包括：最大化降噪减振、保持轨道几何参数（TOR）、利用现有孔位中心、保留BH钢轨与关键协议，并通过EN13481 Cat C测试完成所有工作，同时确保足够的耐久性。

The Delkor Egg baseplate helps to reduce structure-borne vibration and noise. It is comprised of a top plate and base frame that are vulcanized (bonded) together by means of a natural rubber element which helps achieve a very low static stiffness while still ensuring a high degree of rail stability.

Delkor Egg基板可降低结构振动与噪音。其由顶板与底座框架通过天然橡胶元件硫化（粘合）而成，既能实现极低静态刚度，又能确保轨道高度稳定性。

Endurica’s tools help Delkor to fulfill regulatory requirements on part durability and allows rubber stiffness to be optimized for the type of stock and speed.

Endurica工具帮助Delkor满足部件耐久性的法规要求，并针对车辆类型与速度优化橡胶刚度。

Delkor’s client, UK-based Network Rail Acceptance Panel (NRAP), gave full acceptance of the solution.

Delkor的客户英国Network Rail验收委员会（NRAP），已全面认可该解决方案。

Endurica Value Add for Delkor Rail:

① Save costs of multiple physical tests for design iterations
② Make the best design decisions for durability
③ Shorten product development cycles

Endurica为Delkor Rail带来的价值：

① 节省多次设计迭代的物理测试成本
② 为耐久性做出最佳设计决策
③ 缩短产品开发周期

Before Endurica, we went through 40+ design iterations trying to reduce the strain amplitude as much as possible. We also went through 4 or 5 rounds of physical testing before a successful test.

Since we adopted Endurica CL, we have been able to compare the fatigue life for new designs against previous designs that we have been successful with. This has meant that we can produce a suitable design with only a handful of design iterations and a single physical test.
— Liam Turbet Technical Manager Delkor Rail Pty Ltd

使用Endurica前，我们进行了40多次设计迭代以尽可能降低应变幅值，还需经过4-5轮物理测试才能成功。

自采用Endurica CL后，我们可将新设计的疲劳寿命与既往成功设计对比，仅需少量迭代与一次物理测试即可完成设计。
